A short stout needle should be employed, the puncture being preferably made under ethyl-chlorid anesthesia, as the pressure necessary to raise the tissue causes considerable pain.
To further facilitate the injection the operator should raise the skin with the needle introduced subcutaneously.
Only one injection of small amount (10 to 15 drops) should be done at a sitting. The injected mass, unless too easily introduced, and thus forming a tumefaction, need not be molded out, since the pressure of the skin overlying it will accomplish it more satisfactorily, while the pressure required in molding tends only to press out more or less of the mass, thus lessening the benefit of the operation.
A second sitting must be undertaken in not less than one week, or even later, if a subcutaneous dissection has been done.
The secondary treatment should be followed as heretofore described. The reaction, for even a small injection in these cases, is usually considerable.
Interciliary Furrow
This deformity is usually spoken of as a frown. It may be said to be congenital, when it appears in early life, but is commonly acquired through the habit of frowning.
The furrow may be a simple linear one or made up of a number of furrows. The author has been called upon to correct one made up of six distinct furrows.
The furrows or creases radiate upward and outward, conelike from a point beginning at the root of the nose.
